This documentary film is directed by Dean Johnson, and Frank Smith for Taiwan PTS (Public Television Station) is about Taiwan's most remote mountain village which took 15 months to produce. It will be broadcasted at 10 pm on June 30, Taiwan time.
Above information is from its Office website http://www.pts.org.tw/smangus/eng/Storyen.html
Smangus now becomes a popular tourist spot for the outdoor lovers in Taiwan not because of this documentary. After the road was built in 1995, outsiders can assess this beautiful area easily and witness the giant secret tree forest which was discovered in 1991. Since, the word has gotten out. I have planed to visit this indigenous village for 2 years but still in a planning mode. If you somehow happen to be in Taiwan for a leisure trip, it will be a good place for you to visit the primative forest and the indigenous village.
Here is its tourist service center website in Chinese Smangus Tourist Service Center You can find the direction, hotel, and other service on the website.
